HYDRooARBoN-BURNER.

SPECIFICATION forming part of Letters Patent No. 674,345, dated May 14, 196i. Application filed April 7, 1899. Renewed October 12, 1900'. Serial No. 32,972. (No model.)

ltain improvements therein for effecting a perfect combustion of the fuel.

The invention therefore consists of a hydrocarbon-burner having certain features of construction and arrangement of parts, all as illustrated upon the accompanying drawings, described in the following specification, and set forth in the appended claims. v Referring to the said drawings, similar reference characters indicate similar parts or features wherever they occur. j

Of the drawings,Figure 1 represents in horizontal section a burner constructed in accordance with my invention. Fig. 2 represents a vertical section on the line 2 2 of Fig. l. Fig. 3 represents a different embodiment of the invention. Fig. 4 represents a section on the line 4. 4. of Fig. 3. l

The present invention while capable of many uses is particularly adapted for the boilers of automobile vehicles, such as set forth in my copending application filed concurrently herewith.

The fire-box comprises a casing 5, above which the boiler (not shown) is located.l In the lower endof the casing is riveted or otherwise secured a ring 6, having a bead 7 and a flange 8, the bead projecting across the end of the casing. A disk or drum-head 9 is supported by the i'ange 8, its edges projecting into the U-shaped portion of4 the bead, and riveted to said disk is a concentric ring 10, to which a second disk or drum-head 11 is secured. The two heads, together with the ring 10, form a burner with-a chamber for the reception of the gas, there being a tube 12 leading thereinto from an aperture 13 in the side of the casing. A plurality of fru'sto-conical or upwardly-tapering open-ended tubes 14. are secured at their ends in the upper and lower walls 1l and 9 of said chamber and afford ducts for the passage of air through the chamber without communicating with the interior thereof. The upper wall or disk l1 is provided with a plurality of small holes or apertures 15, surrounding the end of each tube 14., so that as the air passes'u p through the tu bes it is commingled with the gas which escapes through the said apertures, and a perfect combustion results.

The gasolene or other fuel is stored in a tank or receptacle .and is delivered under pressure to the pipe 16, which passes as a coil 4across the top of the burner beneath the boiler,

where it is subjected to the heat of the iame, to the injector 1'7.k The last-mentioned element is formed with a nozzle 18 and with a longitudinal duct19, communicating with the aperture therein, to receive an automatically- A concavo-conveX diaphragm 31 is placed inside the cylinder-head, and it is connected to the pin or valve 21, which passes through theend of the cylinder and the tube 23, there being a stuffing-box 27 inside the cylinder to prevent the escape of gas. A spring 28 bears against the .diaphragm and against a cross-brace 29 in the cylinder to hold the valve in its open position, there being `a stop 30`on the valve to limit its movement toward said open position. -Y To light the re, a pan of alcohol is placed under the injector and ignited to convert the gasolene therein into gas. The escaping gas is then lighted above the burner in the combustion-chamber and the gasolene in the coil is quickly gasied, so that there is a Vsteady iow to the nozzle. When the p'ressureof steam in the boiler rises beyond a predetermined point, the diaphragm is distended and forces the valve 21 against the pressure of spring 28 toward closed position to reduce the supply of gas until the steam-pressure is lowered.

It is evident that various changes may be IOO made in the apparatus which I have described without departing from my invention. For instance, in Figs. 3 and 4 I have illustrated another embodiment of the invention, in which the burner is formed in sections 34E, supported upon pairs of cross-bars 33, saidsections being substantially sector-shaped or triangular in cross-section. Each section is formed in its upper surface with rows of apertures 36 to emit gas, and it is arranged in line with an inletin the ring 10. The pipe 12 is formed with lateral branches 37, communicating with the inlets 35, and the gas as it leaves the .nozzle passes into the gas-chambers and liows from the apertures into the combustion-chamber. Each casing 34 is provided with hangers 38 to take over the rods 33, as indicated in Fig. 4, and is readily removable. The air rises through the gaschainber through the taperimg slots or ducts between the sections and commingles with the gas, the apertures 36 being inclined, so that the streams of gas are deflected to cross the path of the currents of air.

In both burners there are a plurality of air and gas ducts interspersed across the plane surface thereof, whereby oxygen is supplied in sufcient quantities to causea perfect co n1- bustion of the fuel.

It is to be understood that the term gas as used herein is not intended to specify a fixed gas, but a fuel in gaseous condition, due to the heat imparted to the gasolene or other liquid hydrocarbon as it passes through that portion of the pipe 16 above the burner. While the term vapor might be applied to the fuel as it passes from the pipe 16, I have preferred to employ the term gas, as here- 'inbefore used.

Having thus explained the nature of the invention and described a way of constructingY and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is l. A burner of the character described comprising the casing 5, the ring 6 secured to the lower end thereof and having a ange 8, the disk 9 supported by said flange, the ring 10 rising from the disk 9 and concentric with the casing, and a burner within the ring 10 and provided with a plurality of ducts for air and gas.

2. A burner of the characterdescribed comprising a combustion-chamber, and a burner therein, said burner having inclined walls forming upwardly-flaring fuel-passages, the spaces between said walls forming upwardlytapering air-passages, the upper and lower ends of the air-passages being open, and the upper ends of the fuel-passages having perforations to cause the emission of fine jets of fuel close to the upper ends of the air-passages.

3. A burner of the character described comprising a combustion-chamber and a burner therein, said burner being composed of the ring l0 and the upper and lower walls 11 and 9, the upwardly-tapering air-tubes 14E secured to said walls and open at both ends, the upper Wall l1 being provided with perforations surrounding and close to the upper ends of the tubes I4, and a connection with the space inside the ring and walls for supplying fuel to the upwardly-flaring spaces around said air-tubes.

In testimony whereof I have affixed my signature in presence of two Witnesses.
